Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0029] The electrical control box provided in the embodiments of this application, such as Figures 1 to 7 As shown, it includes: a control panel 100 and a sealing element; a box base 200, on which the control panel 100 is fixed; a box cover 300, on which the sealing element is fixed; wherein, the box cover 300 is mounted on the box base 200, the control panel 100 is located within the space enclosed by the box base 200 and the box cover 300, and the sealing element seals the gap at the abutment of the box base 200 and the box cover 300.

[0030] In this electrical control box, the sealing element is fixedly installed on the box cover 300. When assembling the box base 200 and the box cover 300, the box cover 300 with the sealing element is placed on the box base 200. The sealing element seals the gap at the contact point between the box base 200 and the box cover 300, thus achieving a sealed fit between the box cover 300 and the box base 200. This solution makes the assembly of the electrical control box easier and faster.

[0031] In some examples, Figure 1 , Figure 2 , Figures 4 to 7 As shown, the side of the box base 200 is provided with an annular mating groove 210. The control plate 100 is located inside the area enclosed by the mating groove 210. The periphery of the box cover 300 is placed within the mating groove 210. The sealing element is pressed between the periphery of the box cover 300 and the groove wall of the mating groove 210 to seal the gap between the periphery of the box cover 300 and the groove wall of the mating groove 210. For both mating grooves 210 with a width of less than 4mm and mating grooves 210 with a width of not less than 4mm, the assembly difficulty of this electrical control box is relatively low and the assembly time is relatively short.

[0032] In some embodiments, such as Figure 1 and Figure 7 As shown, the groove wall of the mating groove 210 is provided with a guide part 220. The guide part 220 is configured to guide the periphery of the box cover 300 into the mating groove 210, which can effectively improve the assembly speed of the box cover 300 on the box base 200.

[0033] Alternatively, the guide portion 220 can be configured as a guide slope; or the guide portion 220 can be configured as a guide curved surface, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.

[0034] In one embodiment, such as Figure 1 and Figure 7As shown, the outer end face of the groove wall of the mating groove 210 is provided with a rib. The side of the rib facing the groove opening of the mating groove 210 is set as a guide slope or guide curve. This scheme has a simple structure, is easy to manufacture, and the guide slope or guide curve has a good guiding effect on the periphery of the box cover 300.

[0035] In some examples, such as Figures 2 to 7 As shown, the sealing element includes a first sealing element 410 and a second sealing element 420. The cover 300 includes a first cover body 310 and a second cover body 320. The first cover body 310 has a wiring notch 311. The first sealing element 410 is fixed to the periphery of the first cover body 310 outside the wiring notch 311. The second sealing element 420 is fixed to the second cover body 320. The first cover body 310 is mounted on the base 200, and the first sealing element 410 seals the groove wall of the mating groove 210. The gap at the periphery of the first cover 310, outside the wiring notch 311, is sealed by the second cover 320, which covers the wiring notch 311. The second seal 420 seals the gap at the junction of the groove wall of the mating groove 210 and the second cover 320. The second seal 420 also seals the gap at the junction of the first cover 310 and the second cover 320 (i.e., the second seal 420 also seals the gap at the junction of the opening wall of the wiring notch 311 and the second cover 320). The two ends of the first seal 410 and the two ends of the second seal 420 in the circumferential direction of the mating groove 210 abut against each other. The first seal 410 engages with one part of the mating groove 210, and the second seal 420 engages with another part of the mating groove 210, thus achieving a closed-loop seal between the cover 300 and the base 200.

[0036] In some embodiments, such as Figure 4 and Figure 5 As shown, the first cover 310 includes a top cover wall 312 and an annular opening cover side wall 313. The edge of the top cover wall 312 is connected to one end of the cover side wall 313. The wiring notch 311 includes the opening of the cover side wall 313. The first sealing member 410 is in the shape of an open annulus and is fixed to the other end of the cover side wall 313 (i.e., the end of the cover side wall 313 away from the top cover wall 312).

[0037] It can be, such as Figure 4 and Figure 5As shown, the first sealing member 410 includes a main body portion 411, a connecting portion 412, and a limiting portion 413. The main body portion 411 is located between the connecting portion 412 and the limiting portion 413. The side of the cover sidewall 313 is provided with a mating portion 314. The periphery of the first cover body 310 outside the wiring notch 311 (i.e., the other end of the cover sidewall 313) is placed between the connecting portion 412 and the limiting portion 413 and abuts against the main body portion 411. The connecting portion 412 is fixedly connected to the mating portion 314 to prevent the first sealing member 410 from falling off at the other end of the cover sidewall 313.

[0038] It could be that the connecting part 412 is a hook, and the mating part 314 is a mounting slot, with the hook hooked into the mounting slot; or it could be, as... Figure 4 and Figure 5 As shown, the connecting part 412 is a hook, and the mating part 314 is a hanging hole. The hook is attached to the hanging hole, etc. At this time, the limiting part 413 (on the side of the cover side wall 313 opposite to the hook) seals and covers the hanging hole, so the thickness of the cover side wall 313 can be designed to be smaller. All of the above can achieve the purpose of this application. Its purpose has not deviated from the design concept of this utility model, and will not be repeated here. All of them should be within the protection scope of this application.

[0039] The sealing element can be made of silicone or rubber, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

The control board 100 includes a board body 110 and a heat sink 120 disposed on the board body 110. The heat sink 120 passes through the first heat dissipation hole 315. The electrical control box also includes a third sealing member 500, which seals the gap between the hole wall of the first heat dissipation hole 315 and the heat sink 120, thereby achieving a sealed fit between the hole wall of the first heat dissipation hole 315 and the heat sink 120.

[0041] In one embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the radiator 120 has a stepped structure 121 on its circumference. The third sealing member 500 is in the shape of a closed ring and is sleeved on the outside of the radiator 120 and placed on the platform of the stepped structure 121. The hole wall of the first heat dissipation hole 315 presses the third sealing member 500 on the platform of the stepped structure 121. This solution has a simple structure and is easy to operate.

[0042] In some examples, such as Figures 1 to 3 , Figure 6 and Figure 7As shown, the first cover 310 is also provided with a second heat dissipation hole 316. The control board 100 also includes an inductor 130 and a fourth sealing member 140 disposed on the side of the board 110. The fourth sealing member 140 is arranged around the inductor 130 in a circumferential direction (i.e., the fourth sealing member 140 is in the shape of a closed ring, and the inductor 130 is located inside the area enclosed by the fourth sealing member 140). The hole wall of the second heat dissipation hole 316 is sleeved on the outside of the inductor 130 and seals against the fourth sealing member 140, so as to achieve a sealing fit between the hole wall of the second heat dissipation hole 316 and the fourth sealing member 140.

[0043] In one embodiment, such as Figure 4 , Figure 6 and Figure 7 As shown, the top wall 312 of the cover is provided with a connecting hole 317 and an extension tube 318. One end of the extension tube 318 is connected to the outside of the electrical control box through the connecting hole 317. The other end of the extension tube 318 is sleeved on the outside of the inductor 130 and sealed against the fourth sealing member 140. A heat dissipation channel is formed inside the extension tube 318. The second heat dissipation hole 316 includes the connecting hole 317 and the heat dissipation channel. This solution makes it easier to achieve a sealing fit between the hole wall of the second heat dissipation hole 316 and the fourth sealing member 140.

[0044] The outdoor unit of the air conditioner provided in this application embodiment (not shown in the figure) includes the electrical control box described in any of the above embodiments.

[0045] This air conditioner outdoor unit possesses all the advantages of the electrical control box provided in any of the above embodiments, which will not be elaborated here.
